They join global giant Siemens, TAFE SA, Flinders University and ICT company, Tier 5 in committing and investing in the Tonsley project.

"This is what the future of manufacturing in South Australia will look like - high tech companies that are globally competitive and working closely with researchers and training organisations," Mr Weatherill said.

"Two weeks ago, the first students started their building and construction training at the Sustainable Industries Education Centre, which brings together the Tonsley TAFE and private training providers.

"As part of the State Government's 'Our Jobs Plan', Tonsley will support new smart specialisation clusters and precincts where future industries can work together to innovate, create new jobs and grow.

The four new commitments include:

Basetec Services - a $9 million investment by the composite pipeline technologies company combined with $1.5 million from the State Government to establish facilities at Tonsley, including a Centre of Excellence in Composites Research and Development.

Signostics Limited - a Thebarton- based international medical devices manufacturer relocating to Tonsley.

ZEN Energy Systems - relocating its head office, research and development, manufacturing, warehouse and distribution operations from Norwood and Woodville to Tonsley.

MAN Diesel and Turbo Australia/Remotenergy - signing an MoU with the State Government which envisages the establishment of a Centre of Excellence at Tonsley to promote clusters around hybrid power development.

BASETECThe company designs develops, manufactures and installs innovative pipe products made of innovative composite materials which have greater resistance to corrosion and last longer than steel pipelines.

Basetec Managing Director Charles Figallo said the Centre of Excellence in Composites Research and Development would be designed for research discoveries, postgraduate education, national and international linkages and commercial outputs.

"We have existing research collaborations with the Ian Wark Research Institute and will extend that to other education and research partners, including Flinders University and TAFE SA, both of whom will be located close to us at Tonsley. "Our company is looking to collaborate and innovate to grow and prosper and we see Tonsley as the ideal place to do this," Mr Figallo said

SIGNOSTICSThe company is an international medical device company which designs and manufactures portable, lightweight handheld ultrasound devices. Signostics has signed an agreement to lease a portion of the existing administration building and will relocate its Thebarton operations and its 15 staff to Tonsley later this month.

The company then plans to move from the administration building into a pod within Tonsley's iconic main assembly building in the second half of 2015.

Signostics CEO, Warren Ortmann said the company had reached the limits of available space at its Thebarton location and saw the move to Tonsley as an opportunity to be part of South Australia's advanced manufacturing future. "We are committed to helping make Tonsley a national centre for the development of medical device technologies and look forward to working closely with the research providers on site to grow the industry in South Australia" Mr Ortmann said.

ZEN Energy SystemsThe company is the largest solar provider in South Australia across residential, commercial and utility markets and will lease several spaces within TAFE SA's Sustainable Industries Education Centre.

Chief Executive Officer of ZEN Energy Systems, Richard Turner said moving the company's operations to Tonsley was an important step forward in ZEN's expansion strategy. "Moving in with other advanced operators and educators into one interactive campus can only foster greater innovation. This benefits not just our company, but the entire state," Mr Turner said.

Remotenergy and MAN Diesel and Turbo AustraliaExcecutive Director of Remotenergy, Barry Harrop said there were tremendous opportunities in SA to establish a hybrid energy solution to power and water issues and for the State to become a globalleader in hybrid energy systems.

Managing Director of MAN Diesel and Turbo Australia, Larry Silva said the MoU with the State Government envisaged establishing a Centre of Excellence at Tonsley to promote clusters aroundhybrid power and water development.
